A lawless type class that specifies conversions from Task
to similar data types (i.e. pure, asynchronous, preferably
cancelable).

Value members
Abstract methods
Converts Task[A] into F[A].
Converts Task[A] into F[A].
The operation should preserve referential transparency and if
possible runtime characteristics (e.g. the result should not
block threads if the source doesn't) and interruptibility
(although this isn't possible for conversions to
cats.effect.Async data types that are not also Concurrent).

Composes two instances of FunctionK into a new FunctionK that transforms a cats.data.EitherK to a single functor.
Composes two instances of FunctionK into a new FunctionK that transforms a cats.data.EitherK to a single functor.
This transformation will be used to transform left F values while
h will be used to transform right H values.
